Shaqada gaarka ah ee magnesium oxide ee batteriga lithium

Electrode carbon carbon galaas ka samaysan nano oxide waxay leedahay sifooyin kala duwan, sida xasiloonida wanaagsan ee baytariyada, conductivity sare, daahirsanaan sare, lahayn gaas in Electrode Essence.Dib-u-cusboonaynta dusha fudud, awoodda hydrogen iyo oksijiinta yaryar, qiimo jaban, iwm. Si kastaba ha ahaatee, kuwan ayaa si guud loo sheegay, markaa waa maxay saamaynta gaarka ah ee magnesium oxide ee baytariyada lithium?

Marka hore, dooro dhexroor 10-100g / L ah 10-100g / L dhexroor u dhexeeya 0.05-10 μm TiO2, SiO2, Cr2O3, ZrO2, CeO2, Fe2O3, BaSO, SiC, qayb Mg;Alaabta loo sameeyay sida lithium ions waxay leeyihiin sifooyin dallacado wanaagsan iyo hufnaan dheecaan leh, awood sare, iyo waxqabadka wareegga dhiigga oo deggan.

Marka labaad, batteriga lithium-ka walxaha togan, nano-magnesium oxide sida dopant conductive, waxay soo saartaa magnesium doped lithium birta manganese fosfate iyada oo loo marayo sababaha hagaajinta, oo sii sameeya qaab-dhismeedka nano-qaabka walxaha elektrodegga ah.Awooddeeda dhabta ah waxay gaartaa 240mAh/g.Noocan cusub ee walxaha korantada togan ayaa leh sifooyinka tamarta sare, badbaadada, iyo qiimaha hooseeya.Waxay ku habboon tahay baytariyada lithium-ion dareere iyo kolloidal, polymers-yar iyo dhexdhexaad ah, gaar ahaan baytariyada awoodda sare leh.

Kadibna, awoodda iyo waxqabadka wareegga ee bateriga lithium manganate spinel ayaa la hagaajiyay.In batari lithium ion electrolyte leh spinel lithium manganate sida walxo togan, nano-magnesium oxide waxaa lagu daraa sida deacidifier si loo saaro acid, qadarka dheeraadka ah waa 0.5-20% miisaanka electrolyte.Marka la gooyo electrolyte-ka, waxa ku jira aashitada bilaashka ah ee HF ee ku jirta elektrolytka waxa la dhimayaa in ka yar 20ppm, taas oo yaraynaysa kala dirida HF ilaa LiMn2O4, waxaanay wanaajisaa awoodda iyo waxqabadka wareegga LiMn2O4.

Ugu dambeyntii, tallaabada ugu horreysa, nano magnesium oxide oo ah nidaamiye pH ah ayaa lagu qasi karaa xalalka alkali iyo xal ammonia oo ah walax isku dhafan, waxaana lagu daraa xal isku dhafan oo biyo ah oo ka kooban cobalt iyo nikkel cusbada si ay ula socdaan Ni-CO hydroxides. .

Talaabada labaad waa in lagu daro lithium hydroxide Ni-CO hydroxide ka kooban, iyo isku darka daaweynta kuleylka 280-420 °C.

Talaabada saddexaad, sheyga ka soo baxa tallaabada labaad waxaa lagu daaweeyaa kulaylka deegaanka 650-750 ° C, taas oo la xiriirta wakhtiga wada-dhaqashada.Celcelis ahaan cabbirka qayb ka mid ah oksaydhka isku-dhafka ah ee lithium ayaa hoos u dhacaya ama cufnaanta bulk ayaa si habboon u kordheysa.Marka lithium composite oxide loo isticmaalo sida walxaha firfircoon ee anode, batari lithium ion sare leh ayaa la heli karaa, iyo qadarka dhabta ah ee magnesium oxide waxay ku xiran tahay qaacidada gaarka ah.
